Definitions

  • the invention relates to a laminated glass pane with a mounting hole and a method for its manufacture.
  • Motor vehicles typically have operable side windows. These side windows consist of a pane of glass that can be moved, essentially by vertical displacement, thus opening and closing the window. To enable the window to move, it is connected to a mechanism inside the vehicle body.
  • ESG tempered safety glass
  • These side windows are typically equipped with one or more holes near the bottom edge, which serve to connect them to the sliding mechanism. Such holes are relatively easy to create in ESG glass and allow for simple and very stable installation.
  • VSG side windows are becoming increasingly common, especially in higher-priced vehicles. These side windows consist of two non-tempered glass panes bonded together by lamination over a thermoplastic interlayer (typically a PVB film). These side windows are lighter than tempered safety glass (ESG) side windows and improve acoustic comfort and security within the vehicle. Because VSG windows with perforations are more difficult to manufacture and less stable than ESG windows, they are conventionally attached to the sliding mechanism in a different way: a holder is clamped or glued to the lower edge.
  • ESG tempered safety glass
  • the US 2008/0092464 A1 Disclosing a laminated glass pane with a mounting recess into which components rotatable from both sides, each with an off-center hole, are inserted. By rotating the components relative to each other, the holes can be aligned, resulting in a mounting hole of reproducible shape and size, regardless of any misalignment of the glass panes.
  • the mounting system according to US 2008/0092464 A1 However, due to its complex design, it is complicated and prone to errors.
  • CN 104476855 A reveals a composite disc with a one-piece polymeric reinforcing element that is injection-molded.
  • DE 4224694 A1 discloses a composite disc with a glass retaining element in which a threaded bolt with a surrounding sleeve is used.
  • the present invention is based on the objective of providing an improved laminated glass pane with a mounting hole which, despite a possible offset of the glass panes, allows the attachment of add-on parts, fastening devices or the like and is easy to manufacture.
  • the laminated glass pane according to the invention comprises at least a first pane and a second pane, which are bonded together via a thermoplastic interlayer.
  • the laminated glass pane according to the invention has at least one opening. The opening extends through the entire laminated glass pane, i.e., through the first pane, the interlayer, and the second pane.
  • Laminated glass is designed to separate an interior space from its external environment. As a vehicle window, it separates the interior from the outside.
  • the two panes can therefore be referred to as the outer pane and the inner pane.
  • the inner pane is the one facing the interior when installed, while the outer pane faces the outside.
  • the first disk, the second disk, and the intermediate layer each have a hole. These holes overlap completely or at least partially, so that the penetration is formed by the overlapping areas of the holes.
  • the holes in the glass panes and preferably also in the interlayer should be the same size.
  • This problem is particularly pronounced with curved laminated glass panes, as commonly used in the automotive industry, because the curvature of the panes leads to further problems with the alignment of the holes.
  • Such an offset can cause problems with the intended use of the feedthrough.
  • a component is attached to the feedthrough, for example, a holding device or a mechanism that holds and moves the pane, or an attachment.
  • An offset which usually occurs unintentionally and is not reproducible, can disrupt the attachment because the feedthrough, which is essentially the intersection of the overlapping holes, is not exactly the same and consistent within the production run.
  • the laminated glass pane is equipped, according to the invention, with a one-piece polymeric element.
  • the edge of the opening is provided with the compensating element.
  • the compensating element does not completely close the opening, but rather also has or forms a through-hole or opening.
  • This hole in the polymeric element extends through the opening of the laminated glass pane, i.e., it is located within the opening of the laminated glass pane.
  • the compensating element ensures that each laminated glass pane in a production series has a mounting hole of the same size, because the size and shape of the mounting hole are defined by the through-hole in the polymeric element. Any misalignment between the glass panes is irrelevant; it is compensated for by the polymeric element.
  • the polymeric element can therefore also be referred to as the compensating element. Due to its one-piece construction, the compensating element is very robust, the connection with the pane is very stable, and its manufacture is comparatively simple. These are major advantages of the invention.
  • the polymer element is designed and suitable for compensating for misalignment between the panes.
  • the polymer element is further designed and suitable for attaching a component or fastening element to the pane, in particular by inserting a fastening section, for example a fastening pin, into the hole of the polymer element.
  • the polymer element is further designed and suitable for controlling the transfer of forces acting on the laminated glass pane by the component or fastening element attached to the pane, preferably distributing them evenly across the individual panes.
  • the edge of the penetration is the edge of the laminated glass pane located within the penetration, which defines the penetration and comprises the corresponding side edges of the two panes and the interlayer.
  • the compensating element is arranged on a portion or the entire edge of the penetration.
  • the compensating element can be in direct contact with this portion or the entire edge of the penetration or connected to it via an adhesion promoter or adhesive.
  • the compensating element is located entirely within the surface of the laminated glass pane. This means that the compensating element does not protrude beyond the side edges that define the laminated glass pane. It is confined to the area within the laminated glass pane and therefore differs fundamentally from polymer fasteners that are attached in the area of a side edge and protrude beyond it to provide a fastening point in the protruding area.
  • the offset between the holes in the first and second discs is, for example, up to 5 mm or up to 2 mm.
  • the invention is particularly advantageous, of course, when an offset greater than 0 mm occurs, for example, greater than 0.1 mm.
  • discs with a compensating element would also be provided which, due to manufacturing variations, exhibit no offset.
  • the offset can, for example, range from 0.1 mm to 5 mm or from 0.1 mm to 2 mm.
  • the holes in the first and second discs can be the same size. Alternatively, the holes can also be different sizes. For example, during manufacturing, it might be easier to position the discs by placing a smaller hole within the area of a larger hole.
  • the compensation element according to the invention compensates for the size difference that occurs.
  • the size of the opening in the laminated glass pane and the size of the hole in the compensating element depend on the specific requirements of each case. Typically, the size of the opening and hole ranges from 5 mm to 100 mm, most commonly from 10 mm to 30 mm. These are typical sizes for mounting holes. Naturally, the size of the hole in the compensating element is smaller than the size of the opening in the laminated glass pane, since the compensating element is located within this opening.
  • the size of the hole in the compensating element is preferably 50% to 90% of the size of the opening, and particularly preferably 60% to 80%. This effectively compensates for any misalignment between the panes, provides a stable connection point for attachments, and does not excessively reduce the size of the mounting hole, thus ensuring easy connection to the attachment.
  • the hole in the fastener is preferably essentially circular, which is the design standard for most conventional fastening systems or attachments. However, depending on the specific requirements, the hole can also have any other shape, for example, an elliptical or irregular shape.
  • the polymer element is formed by injection molding within the feedthrough, completely covering the edge of the feedthrough and in contact with the entire edge.
  • the polymer element also covers a circumferential area adjacent to the feedthrough on the opposite surfaces of the first and second panes (outer surfaces of the laminated glass pane).
  • the polymer element is directly injection molded onto the laminated glass pane.
  • Such a compensating element is very robust and stable and less prone to defects than, for example, compensating elements that are formed in two parts, inserted into the feedthrough from both sides, and joined together there, for example, via a screw or snap-fit connection.
  • the material thickness of the injection-molded compensation element measured perpendicular to the edge of the feedthrough and, optionally preferably, also perpendicular to the circumferential area of the outer surfaces, is preferably from 1 mm to 10 mm, particularly preferably from 1.5 mm to 5 mm, and especially from 1.5 mm to 3 mm.
  • the compensating element which is covered by the existing material, preferably has a width of 2 mm to 20 mm, more preferably 3 mm to 10 mm, and particularly 3 mm to 5 mm. This ensures a very stable connection between the laminated glass pane and the compensating element. While the width should be at least 2 mm or 3 mm to guarantee sufficient stability, the upper limit is technically determined only by the edges of the pane and is otherwise unrestricted, although an excessively large width increases the material costs of the compensating element.
  • the polymeric element is a tolerance ring.
  • Tolerance rings are known to those skilled in the art. They are strips with a profiled surface design, the ends of which are joined together in a ring-like fashion, thereby forming a hole. Tolerance rings are mostly used as friction-fit connecting elements, particularly in mechanical engineering. There, they are made, for example, of spring steel. The inventors have recognized that a polymeric tolerance ring can be used to form the hole according to the invention and to compensate for the misalignment of the holes in the glass panes without entailing the risk of damaging the laminated glass pane.
  • the material thickness of the tolerance ring is preferably from 1 mm to 5 mm, particularly preferably from 1 mm to 2 mm.
  • the polymeric compensation element preferably contains at least one thermoplastic polymer.
  • the polymer can be reinforced with glass fibers or glass beads to have a similar coefficient of thermal expansion to the glass panes.
  • Preferred materials are, in particular, polyamide or polybutylene terephthalate, but polyethylene, polypropylene, polystyrene, polyoxymethylene, polycarbonate, polymethyl methacrylate, polyester, polyvinyl chloride, polysulfone, polyethersulfone, polyetherketone, or polytetrafluoroethylene can also be used. Mixtures or copolymers can also be used.
  • the compensation element contains at least one thermoplastic elastomer, which allows even minor deviations in the pane arrangement, such as angular deviations, to be compensated.
  • the compensation element is particularly preferably made of one of the aforementioned materials.
  • the laminated glass pane according to the invention can be flat or curved in one or more spatial directions.
  • the compensation element according to the invention is particularly advantageous for curved laminated glass panes because it is especially difficult to align the holes in the individual panes without offset.
  • the laminated glass pane is preferably a motor vehicle window, in particular a window of a passenger car, which are typically curved.
  • the laminated glass pane according to the invention is an openable side window of a motor vehicle, in particular a passenger car.
  • side windows have several, in particular two, openings.
  • the opening(s) are arranged in the region of the lower edge (facing the ground when installed), where they are concealed within the vehicle body in both the open and closed states of the window.
  • the hole in the compensating element is designed for connection to a lifting mechanism located in the vehicle body to secure the pane, in particular by inserting a fastening section of the lifting mechanism, for example, a fastening pin, into the hole. This eliminates the need for complex brackets attached to the lower edge of the side window, which are currently common for laminated side windows.
  • the laminated glass pane according to the invention can also be used for other applications.
  • the hole can serve to attach components to the laminated glass pane.
  • the laminated glass can be a vehicle roof window, with an antenna mounted in the hole.
  • the laminated glass can be, for example, a transparent radiator, with holes provided for wall mounting.
  • the first and second panes preferably contain glass, in particular soda-lime glass.
  • one or both panes can contain rigid plastics, in particular polycarbonate or polymethyl methacrylate.
  • the thickness of the panes can vary widely and thus be ideally adapted to the specific requirements.
  • the thickness of the first and second panes is 0.5 mm. up to 10 mm and preferably from 1 mm to 5 mm, most preferably from 1.4 mm to 3 mm.
  • the first pane, the second pane, or the intermediate layer can be clear and colorless, but also tinted, opaque, or colored.
  • the first and second panes can be made of non-tempered, partially tempered, or tempered glass.
  • the thermoplastic interlayer is formed by at least one thermoplastic connecting film.
  • the thermoplastic connecting film contains at least one thermoplastic polymer, preferably ethylene vinyl acetate (EVA), polyvinyl butyral (PVB), or polyurethane (PU), or mixtures, copolymers, or derivatives thereof, particularly preferably PVB.
  • the thickness of the thermoplastic connecting film is preferably from 0.2 mm to 2 mm, particularly preferably from 0.3 mm to 1 mm, for example, 0.38 mm or 0.76 mm.
  • the hole in the thermoplastic interlayer can be formed before process step (b). Then, in process step (b), the holes in the panes and the hole in the interlayer are arranged overlapping. However, the laminated glass can also be produced without this. A hole is laminated into the thermoplastic intermediate layer, and then the hole is created in the intermediate layer, resulting in the through-hole.
  • the holes in the individual discs are produced by drilling or other methods known to those skilled in the art.
  • the hole in the intermediate layer is preferably produced by cutting or punching.
  • the individual panes are preferably bent before lamination, using any standard bending method. Bending preferably takes place after the holes have been drilled in the individual panes, because flat panes are easier to drill.
  • step (d) the area of the laminated glass pane with the feedthrough is arranged between two injection molds, and the polymer element is injected directly onto the edge and, optionally, a circumferential area surrounding the feedthrough of the outer surfaces of the laminated glass pane.
  • the laminated glass pane can be pretreated with a primer or adhesion promoter for improved adhesion.
  • step (d) a polymeric tolerance ring is inserted into the feedthrough, which forms the hole according to the invention.
  • Lamination of the laminated glass is carried out using conventional methods known to those skilled in the art, such as autoclave processes, vacuum bag processes, vacuum ring processes, calender processes, vacuum laminators, or combinations thereof.
  • the bonding of the first and second panes typically occurs under the influence of heat, vacuum, and/or pressure.
  • the invention is explained in more detail below with reference to a drawing and exemplary embodiments.
  • the drawing is a schematic representation and not to scale. The drawing does not limit the invention in any way.
  • FIG. 1 shows a top view of a laminated glass pane V, designed as an opening side window of a passenger car.
  • the laminated glass pane V is intended as a side window for the front side window of a passenger car, which can be opened by lowering the side window.
  • the laminated glass pane V has two mounting holes near its lower edge, which are provided for connecting the laminated glass pane V to a lifting mechanism in a vehicle body.
  • a bracket of the lifting mechanism can be passed through the mounting holes and fastened, so that the pane is securely connected to the lifting mechanism.
  • the mounting holes are formed by openings 4 in the laminated glass pane V, into which a polymeric element 5 is inserted. This element has a through hole 6 that extends through the opening 4.
  • the edges of the opening 4 are provided with the polymeric element 5, without completely sealing the opening 4.
  • FIG. 2 Figure 1 shows a cross-section through a conventional laminated glass pane V without a polymer element 5.
  • the laminated glass pane V consists of a first pane 1 and a second pane 2, bonded by a thermoplastic interlayer 3.
  • the two panes 1 and 2 are made of, for example, soda-lime glass and each has a thickness of 2.1 mm.
  • the interlayer 3 is formed, for example, by a PVB film with a thickness of 0.76 mm.
  • Each pane 1 and 2, as well as the interlayer 3 has a hole, the overlap of which forms the opening 4.
  • the holes in the panes 1 and 2 are not perfectly aligned, but have an offset x.
  • This offset x reduces the effective size of the opening 4 and means that the exact shape of the opening 4 is not constant within a production run. This can make it more difficult, or in the worst case impossible, to install the lifting mechanism as intended in passage 4.
  • the first pane 1 is intended as the outer pane, the second pane 2 as the inner pane.
  • the facing surfaces II, III of panes 1, 2 are connected via the intermediate layer. 3 connected to each other, the surfaces I, IV of the panes 1, 2 facing away from each other form the outer surfaces of the laminated glass pane V.
  • Fig. 3 shows a cross-section of the design according to Figure 1 , which is not claimed in the patent claims.
  • the polymeric element 5 covers the edge K of the opening 4 as well as a region of the outer surfaces I, IV of the laminated glass pane V, which surrounds the opening with a width of 5 mm.
  • the material thickness of the polymeric element 5 is, for example, 3 mm.
  • the polymeric element 5 is injection-molded directly onto the laminated glass pane V by means of an injection molding process. It consists, for example, of polyamide 6.6.
  • the polymeric element has a hole 4 with a diameter of, for example, 1.5 cm, which serves as the actual mounting hole.
  • the offset x is compensated by the polymeric element 5 so that all manufactured panes have a mounting hole of identical size and shape.
  • FIG. 4 Figure 5 shows a cross-section through an embodiment of the invention.
  • the polymeric element 5 is a tolerance ring that is inserted into the feedthrough 4 and forms a hole 6.
  • the offset is advantageously compensated and a stepless mounting hole is created.
  • Fig. 5 shows a flowchart of an embodiment of the method for manufacturing a laminated glass pane according to Figure 1 .
